“Humanizar”: aprendizajes sobre alteridad, salud y futuro en una experiencia de investigación compartida

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT The visit to Bogotá of a fééeneminaa (Muinane) friend, Célimo Nejedeka Jifichíu, and in particular, his work in researching and transmitting traditional health knowledge, offer the pretext to navigate the relationship between elements that at first glance seem distant from each other: indigenous imaginaries about otherness, their visions of ...

Gestural Sequences in Wild Spider Monkeys (Ateles geoffroyi)

American Journal of Primatology, Volume 88, Issue 4, April 2026.
Geoffroy's spider monkeys produce gestural sequences in the wild, mostly during aggressive, playful and sexual interactions. ABSTRACT To date, research on gestural communication in species other than great apes has been quite limited, especially in their natural habitat, although including a broader range of species in different settings is essential ...

The Cinderella tree, Quillaja saponaria – A soap story

PLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 439-451, March 2026.
Our current understanding of plants has been shaped by the entwining of different cultures. The Chilean soapbark tree, traditionally valued as a source of natural soap, was shown by serendipitous research in France in the 1900s to produce compounds that can boost the immune response to vaccines.

Phytochemical diversity of naturally regenerated plants in a biodiversity enrichment experiment

Journal of Ecology, Volume 114, Issue 3, March 2026.
Tree islands established within an industrial oil palm plantation promoted the recovery of phytochemical diversity through natural regeneration. Ten years after planting, untargeted metabolomics of 76 regenerating woody species detected 27,122 phytochemical features, including many novel compounds. Larger islands supported higher woody species richness
